Those wire safety barriers

The RTA have installed the cheese cutter barriers on the hume at
mundoonen ranges, just north of yass. the fences are 1 km long with no
anchor points other than the ends. One of the fences is convex to the
road around a long right hand bend on the southbound side, that makes
the tension pull away from the road, how does this "catch" vehicles
which stray off the road? they would have to travel through the curve of
the fence before they would take tension and "catch " the vehicle. thus
putting them well into the oncoming lanes.

I'd guess that the posts, although they do not look it, are quite
strong, and that the fence would probably restrain a car a long time
before it got to the other side of the median. On the other hand, I
ubderstand these fences are nor designed to be used on concave curves.
I assume the wire could slacken and create a pocket that could catch the
vehicle and cause it to flip in a rather unpredictable manner.

They do strange things but then its a government organisation.

In Wollongong they had a wide barrier of hay bales that had trees growing
on them. For some strange reason they have removed quite a bit of this and
put the dreaded rider dicer in its place

 

"Cheese cutter barriers"

Shheeessh! If you believe that you're a fuckwit....oh wait! You do!

Fuckwit.

You know, I was thinking (don't everybody get up)

but what if they installed a plastic curtain panels that go from top to
bottom that would cover the wire, thus any biker running into them, the
force would be spread evenly into it, a hard/soft plastic that's thick
enough not to brake with a frontal impact.

being simple plastic bits if a car hit them the wire rope barrier would
still work if not better as the force is spread between the cables, probably
would help it stop acting like a band saw too...

Who got diced?

It's not actualy the wire rope that's the problem it's the exposed posts.
The wire rope will absorb and distribute the force to a certain extent but
the rigid posts will just snap you.

An interesting article on road side barriers.

mundoonen ranges,

 

I'm actually concerned over the ornage 'poles' erected in the middle of the
M4 either side (east and west) of the M7 cloverleaf thing. If a rider were
to go over the wire fence (not unthinkable, they arent that high), I wouldnt
like to get tangled amongst those poles.

What are they for? Only reason I can think of is decoration.

The actual problem with WRB's isn't the wire rope, it's the posts used
to hang the rope off. Well, the majority of reported deaths involving
riders and WRBs any way

(no I can't give the cite, I can't remember where I got the info - Aust
College of Road Safety Meeting I think)

 

Why the F@$#wit ?
whats with the attitude?

Mick

 

Just to save myself googling (I have beer to drink), has there ever been a
death that has "cheese-cuttered" a rider?

Cheers

It is still harsh week, Mick. For some people, this is their only social
interaction. You have to smile sweetly for people like that.

Hammo

 

er... I wouldn't recommend 'smiling sweetly' at JustAl. You never know
where you might end up.

Moike

(not that there's anything wrong with that....)

 

Wise words of experience from Moike?

Hammo

 

Last time he smiled sweetly it changed his life!

justAL

 

Because they aren't cheese cutters they're back breakers and I'm sick of
hearing motorcyclists argue this point as all it does is to suggest how
ignorant the biker population is.

And it's week 282 of harsh week.


justAL

 

Yes, but afaik it wasn't the wires that sliced and diced him, it was the
posts (plural). The corpse however was sans (most or all) limbs and the
head wasn't well attached as I understand it.

JL

 

OY ! I resemble that remark, well I'll have you know my life came in off
back order last week

JL

 

A suspect a bloke up the road would call them limb extractors if he could
still talk... or breathe.

 

Doesn't sound too good.

Was this in Australia? Looks like I'll have to google it after all...
